Prompt Versioning and Regression Evals

What this skill teaches

Manage prompts like production code with versions, eval sets, release notes, and rollback criteria.

This skill is based on 2026 demand around GitHub AI-agent repositories, Product Hunt prompt and agent launches, X discussions about Claude Code skills, and the rise of reusable agent workflows.

Workflow

1. Define the user job, environment, target model or agent, and acceptable autonomy level.
2. Collect official docs, repository evidence, community signals, and practical examples before writing instructions.
3. Turn the workflow into reusable steps with inputs, outputs, constraints, and review points.
4. Add failure modes: missing context, stale sources, prompt injection, over-broad permissions, weak evals, or unclear ownership.
5. Test the skill on a small real task, revise the trigger, and document when not to use it.

Quality gate

• The skill must be recognizable without the title because it contains domain-specific steps.
• It must produce an artifact a human can inspect: checklist, table, plan, prompt, eval set, or implementation brief.
• It must state boundaries and escalation points instead of encouraging blind automation.
• It must include at least two source types: official/project sources and community or launch evidence.
